About

Strategic yet hands-on leader with 9+ years of experience guiding private and public organizations through transformation. I bring a background in management consulting and startup leadership, with a strong focus on implementation, collaboration, and people development. I’ve led diverse teams and overseen key people-related processes—including recruitment, onboarding, performance frameworks, and learning & development—ensuring that structures grow in step with ambition. In the international development sector, I served as Chief of Staff, translating leadership vision into operational clarity and supporting cross-functional teams across geographies. As co-founder of ImpactLens, I also helped design a scalable framework to embed social and environmental impact into strategic decision-making—working at the intersection of purpose, systems, and execution. I thrive in fast-paced, international environments where people, process, and culture are critical to growth—and where trust, structure, and empathy turn vision into reality. I particularly enjoy building up initiatives from scratch and creating the foundations for long-term, values-driven success.
